Genes affected

LMOD1 (HGNC:6647): (leiomodin 1) The leiomodin 1 protein has a putative membrane-spanning region and 2 types of tandemly repeated blocks. The transcript is expressed in all tissues tested, with the highest levels in thyroid, eye muscle, skeletal muscle, and ovary. Increased expression of leiomodin 1 may be linked to Graves' disease and thyroid-associated ophthalmopathy. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.1009G>A (p.V337I) alteration is located in exon 2 (coding exon 2) of the LMOD1 gene. This alteration results from a G to A substitution at nucleotide position 1009, causing the valine (V) at amino acid position 337 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
